Public bug reported:
Binary package hint: linux-image-2.6.38-3-generic
This sky2 module was working properly on kernel 2.6.35. But on this
kernel version causes problems when the network interface is connected
to a 10/100Mbps switch. It works properly on a Gigabit switch.
There is a heavy packet loss:
